What the heck does the V in HVAC stand for?

ventilation_passive_houseA lot of people refer to their air conditioner/heater simply as “their AC,” but hear it referred to as HVAC.  What is that all about? HVAC is a common term used in the heating and cooling industry. It stands for “heating, ventilation and air conditioning.”  Those are the three functions combined into most modern heating and cooling units.

The one that confuses people is the V – ventilating.  This often overlook aspect of modern systems is one of the most important.  The system provides ventilation, reduces air infiltration, and maintains pressure relationships between spaces. The means of air delivery and removal from spaces is known as room air distribution.

Without that distribution of air, the heat or cool would not travel.  Air movement is what ultimately makes the entire system work.
